In 1970, Japanese scholars studied the phase diagram of iron oxide microcrystalline formation, which laid a theoretical foundation for the preparation method of iron oxide yellow crystal seed. According to the research results, iron yellow crystal seeds can be formed under acidic or alkaline conditions. Because iron yellow is a crystal structure, in order to crystallize into pigment particles, it must first form crystal nucleus and become crystal seed, and then the crystal nucleus grows into iron yellow. Otherwise, only thin and dim color paste can be obtained, which does not have pigment properties. Acid process can be divided into iron sheet process and drop addition process.

  • Further complexity arises from the differentiation of HPMC based on its viscosity grade. The viscosity grade indicates the thickening power of an HPMC solution and is typically measured in centipoise (cP). Low-viscosity grades (10-100 cP) are ideal for wet granulation processes due to their enhanced solubility. Medium-viscosity grades (3000-6500 cP) find use in sustained-release matrices, while high-viscosity grades (over 10,000 cP) are employed for thickening and stabilizing suspensions Medium-viscosity grades (3000-6500 cP) find use in sustained-release matrices, while high-viscosity grades (over 10,000 cP) are employed for thickening and stabilizing suspensions Medium-viscosity grades (3000-6500 cP) find use in sustained-release matrices, while high-viscosity grades (over 10,000 cP) are employed for thickening and stabilizing suspensions Medium-viscosity grades (3000-6500 cP) find use in sustained-release matrices, while high-viscosity grades (over 10,000 cP) are employed for thickening and stabilizing suspensionshpmc types.

  • In ruminants, cellulose is first hydrolysed by ruminal microorganisms into cellobiose, then is fermented to pyruvate and finally volatile fatty acids. The changes of forage to concentrate ratios in the diet significantly affect the number and type of rumen microorganisms and then affect the end products of fermentation. Moreover, the extent of cellulose digestion is a compromise between the rate of hydrolysis and the retention time in the rumen related to the particle size of the forage. The intrinsic digestibility of cellulose depends on the origin and treatment of the forage. As far as cellulose is associated to lignin, hemicelluloses and cutin in natural forages, a wide range of digestibility is observed (30 to 90%). Crystallinity of cellulose decreases the rate but not the extent of digestibility that may reach 80% (Van Soest, 1994).
